Optical coherence tomography as a novel diagnostic tool for distal type chronic thromboembolic pulmonary hypertension.
he new classification of pulmonary hypertension (PH) has been recently updated,1 in which 5 major categories of the disorder have been classified. Among them, pulmonary arterial hypertension (PAH, class 1) and chronic thromboembolic PH (CTEPH, class 4) are characterized as having similar hemodynamic pulmonary circulation despite their different pathological vascular structures. Optical coherenc...

متن کاملPercutaneous transluminal pulmonary angioplasty markedly improves pulmonary hemodynamics and long-term prognosis in patients with chronic thromboembolic pulmonary hypertension.
BACKGROUND Distal-type chronic thromboembolic pulmonary hypertension (CTEPH) is a fatal disease for which a new therapeutic strategy needs to be developed. We examined the effects of percutaneous transluminal pulmonary angioplasty (PTPA). METHODS AND RESULTS We prospectively enrolled 12 patients with distal-type CTEPH. After stabilizing their condition with pulmonary vasodilators, we then per...

OBJECTIVES The aims of this study are (1) to evaluate the safety and feasibility of using optical frequency domain imaging (OFDI) during balloon pulmonary angioplasty (BPA) procedures, (2) to assess the correlations between the vessel area (VA) and luminal area (LA) obtained by OFDI and intravascular ultrasound (IVUS), and (3) to compare inter- and intra-observer variability among measurements ...
متن کاملDrug Therapy in Patients with Chronic Thromboembolic Pulmonary Hypertension
Background: Chronic Thromboembolic Pulmonary Hypertension (CTEPH) results from the obstruction of predominantly major pulmonary vessels by organized blood clots and is one of the causes of pulmonary hypertension. The disease is still underdiagnosed and the true prevalence is not clear. The objective of this study was to determine the clinical characteristics and current management of patients w...
